If an ipr adapter hits a fatal microcode error requiring a reset
while a SATA device is going through EH, it can result in a command
getting issued to the ipr adapter while it is getting reset, which
can cause PCI bus errors. Wait for any outstanding adapter reset
to finish prior to issuing a SATA device reset.

When the aic94xx driver creates ascbs, each ascb is initialized with a
timeout timer.  If there are any ascbs left over when the driver is being
torn down, these timers need to be deleted.  In particular, we seem to
hit this case when ascbs are issued yet never end up on the done list.
Right now there's a sequencer bug that results in this happening every
so often.

CONTROL PHY commands are typically sent when things are really messed
up with the sequencer; however, any other leftover ascb should produce
loud warnings.

This patch implements a REQ_DEVICE_RESET handler for the aic94xx
driver.  Like the earlier REQ_TASK_ABORT patch, this patch defers the
device reset to the Scsi_Host's workqueue, which has the added benefit
of ensuring that the device reset does not happen at the same time
that the abort tmfs are being processed.  After the phy reset, the
busted drive should go away and be re-detected later, which is indeed
what I've seen on both a x260 and a x206m.

The comment at the nesting lock says:

	/* Careful for priority inversions here !
	 * irlmp->links is never taken while another IrDA
	 * spinlock is held, so we are safe. Jean II */
